Link Mode

Description

This menu item defines the mode of operation for an X.25 link as normal, passive, or extended:

zNormal mode is used for normal X.25 service.

zPassive mode allows AI296 to operate with the SCCS application of the AT&T 5ESS. The SCCS application requires redundant links at the 5ESS. These links are called SCC0B and SCC1B. Only one link is active at a time. The 5ESS constantly tries to bring up whichever link is idle. If the 5ESS has SCC0B active, it will try to bring up SCC1B. If SCC1B comes up, the 5ESS will drop SCC0B and send information on SCC1B. Passive mode ensures that either SCC0B or SCC1B will be up, but not simultaneously.

zExtended mode supports passive link capability to the 5ESS over a TCP/IP network. Extended mode ensures that either SCC0A or SCC1A will be up but not simultaneously and will temporarily take down the corresponding link if connections fail or cannot be placed because the corresponding remote link is down.
